HF Analyzer HF 35C (Måler høyfrekvens)
Dette er apparatet for de tekniske
amatører. Apparaet gir en enkel evaluering av høyfrekvent stråling, og
har en audiofunksjon som gjør at man kan høre strålingsmengden.
Apparatet gir og en visning av toppverdier i tillegg til
gjennomnittsverdier.#
This is THE device for technical amateurs –
especially easy to operate. It allows a straight forward assessment of
the exposure, a determination of suitable remedial actions, as well as a
control of their effectiveness.
Even this starter device already
combines all common advantages. The reading shows the total pollution
without any calculation required. The measured values are reliably
displayed directly in the entity corresponding to the building biology
standard values. An acoustic signal proportional to the field strength
with «Geiger-counter-effect» helps identifying regions with increased
exposure. Digital display of 1 µW/m2 up to 1999 µW/m2.
Frequency Range: 800 MHz – 2.5 GHz
Measurement Range: Power flux density: 1 – 1999 µW/m2
Accuracy: Basic accuracy including linearity tolerance : +/- 6dB Zero offset and rollover +/- 9 digits
Sensor: Logarithmic periodic antenna
Audio Analysis: acoustic signal proportional to the field strength with «Geiger-counter-effect»
Signal rating: peak value

Høypass filter HP800_G3
High-pass filter suitable for: HFE35C, HF59B, HFE59B.#
The HP800 increases the measuring accuracy when measuring with the log.-per. antenna in combination with the extremely broad band devices HFE35C and HF59B(Filter included in the scope of supply of the HFE59B).
Why?
The log.-per. antennae are sensitive also for individual frequencies below the specified frequency range. These can be successfully suppressed with the filter, which in turn allows a significantly improved analysis of the measurements with a log.-per. antenna, as the measurements are not impaired by unidentified interference signals.
– This filter helps suppress the lower frequencies. It reaches an attenuation of more than 50 dB (= factor 100,000) below 600 MHz.
– All Gigahertz analysers specified above 800 MHz already come with a similar filter integrated in the basic device. This integration naturally makes no sense for the HFE-types.
– Adaptor plug to be connected to the antenna input socket.
Technical data:
– Accuracy: Attenuation: 10 MHz – 600 MHz < – 50 dB
– Pass band: 0 Hz, 800 MHz – 3000 MHz = -1 dB +/- 0.5 dB
– Return loss: > 12 dB
– Further Questions: Two years warranty
– Weight: 0,03 kg
Scope of delivery:
– High-pass filter
– tightening aid
– manual

* An additional high pass filter applied at 1100 MHz helps differentiating in areas with high levels in the TV bands.
* To be connected between the antenna cable and the antenna input socket of the measuring device (by the operator).
* Cascadable with all amplifiers and attenuators.
* Also allows for a broadband measurement without additional transmission loss, which means the filter can remain attached to the device.
